Predicted to enable several functions, including calcium channel regulator activity; guanyl ribonucleotide binding activity; and magnesium ion binding activity. Predicted to be involved in chromosome organization; metaphase plate congression; and mitotic cell cycle. Located in nucleus. Is expressed in several structures, including clavicle; dorsal grey horn; gut; telencephalon ventricular layer; and tooth. Orthologous to human GEM (GTP binding protein overexpressed in skeletal muscle). [provided by Alliance of Genome Resources, Apr 2022]
